91 WITH ESSES W/JMW fiawf what the diameter of the latter may be, may

number of revolutions of the crank shafts. Thus, supposing the gear wheel 16 to be of the proper diameter to cause the .cam to make one revolution for each five revolutions of the crank shafts, the stock will be cut into thirty-foot lengths, it being understood that the action of this cam on the lever 35 is such as to hold the guide 31 out of line with the shear blades during live revolutions of the crank shafts and then to move said guide into line with the shear blades for the sixth revolution of the crank shafts.

The severed lengths of stock are preferably arranged to be caught in a trough whose lateral walls are formed by the plates 37, which are secured to a series of overhanging arms or brackets 38. The bottom of this trough is formed by a tilting plate 89, which is se cured to a rocker shaft 410, and which is connected by a series of links and levers 41 with the lever 33. The arrangement of these links and levers is such that after each length of stock is deposited in the trough, the bottom plate 39 will be tilted so as to allow the stock to drop as soon as it is cut oil. The arrangement of the links il is such, as will be be seen from Fig. 2, as to form a toggle joint to hold the tilting bottom plate of the trough in its closed position until released by the action of the cam wheel 36.

The machine may be used to advantage in connection with rolling mills, such as mills for rolling blooms, rods, bars and other shapes, the shear being located in line with the rolls which finished the commodity to be cut to length. These rolls may, however, be either finishing rolls or a roll at some intermediate stage in the process of rolling, and 28 and 29 in the drawings may be taken as indicating such rolls. The partly rolled shape can be delivered to the shears and cut to lengths and then fed to another train of rolls and finished. The shear can also be used for shearing finished material either hot or cold.

The advantages of our invention result from the facility with which the machine can be changedto cut the stock into any desired length, the simple change of one of the driving gears for the cam wheel being all that is required. The machine is simple and positive inits operation. It will be understood {that any suitable arrangement of driving gears for the two pairs of crank shafts may be employed; also that the precise arrangement of the gears'for driving the cam wheel may be changed; that any suitable arrangement of the laterally movable guide may be employed, and that various other changes in details of construction and arrangement may be made.

By means of this change rods connecting the cranks of each pair of shafts and each carrying a shear blade, means forfeeding the stock to the machine at the same rate of speed as the speed of rotation of the crank pins of said shafts, a movable guide for the stock normally out of line with the shear blar e, and means for periodically moving said guide into the path of movement of the shear blades; substantially as described.

3. A metal shearing machine having a movable shear blade, a laterally movable feed guide normally out of the line of movement of said shear blade, means for moviiig said guide into the path oi movement of the shear blade, and gearing for actuating said means in time relation to the movementof, the shear blade, said gearing having achange member; substantially as described.

4. In a metal shearing machine, a movable shear blade, a stock guide normally out of line with the path of movement of the shear blade, a movable support for said guide, cam controlled means for moving said support, and gearing for actuating the cam controlled means, said gearing having a change member; substantially as described.

5. A metal shearing machine having a pair of reciprocatin shear blades, each of which is carried by two cranks rotating about different centers, means for rotating the cranks in unison, and means for feeding the stock into the machine at the same rate of movement as the lineal movement of the shear blades on the cranks; substantially as described.

6. In a metal shearing machine, a pair of reciprocating shear blades, a pair. of connected crank shafts for carrying and actuating each blade, gearing for driving all the crank shafts atthe same rate of s eed, stock feeding means, including a lateral y movable guide normally out of line with the patn of movement of the shear blades, and cam controlled means for moving said guide peri odically in time relation to the movement of the shear blades; substantially as described.
